AQQA Aquarium Heater for 60-120 Gallon Fish Tank

The heating water temperature range can be set to 59°F-93°F/15°C-34°C. Press the button for 5 seconds to achieve conversion between Fahrenheit and Celsius degrees. Each press of the button increases by 1°F/°C, with 59 and 93 as a loop, and pressing the number to the highest will return to the lowest number. [Temperature Range 59°F-93°F/15°C-34°C]

When the heating rod leaves the water surface by 2.4 inches, it will automatically power off and display an error code E0. When the heating rod is immersion into water, the error code is automatically repaired. In order to extend the service life, please put the heating rod into the water before powering it on, and take it out after the heating rod has cooled down. [Burned Protection, Safe and Reliable]

When the heating rod detects that the water temperature is 3°F/3°C higher than the set temperature, the current water temperature number will keep flashing to indicate the high temperature alarm and stop heating. It will automatically return to normal once the water temperature drops to the set temperature. [Electricity Leakage Protector, Overtemperature Protection]

Intelligent heating is activated when the water temperature is 1°F/1°C below the set temperature, and heating stops when the set temperature is reached. The red light line indicates heating, the green light line indicates reaching the set temperature, and the light line disappears when an error code has occurred. [Fast Heating, Intelligent Controller]

Due to the heating rod forming scale in the water over time, the accumulation of scale can affect heat dissipation and lead to safety issues. Therefore, we recommend regularly disassembling the heating rod shell to clean the rod body. Quality assurance is provided for one year, and please contact us if you have any questions. [Please Clean Regularly]
